CORN HARVEEJTER AND SHUCKER.

To (ZZZ whom it may concern:

to it known that l, HENRY A. Von dram, citizaen of the United States, residing at Jenerm in the county of Hancock and State of Uhio, have invented certain new and use fulv Improvements in Corn Harvesters and Shockers, of which the following is a specification. reference being; had therein to the arr-mupanying drawing.

My invention relates to improvements in corn harvesters and shockers,. and is of that type which is adapted to simultaneously out two rows of standin corm feed the cut corn to rear shock compartment in which it is compressed, and after being tied into a shock is deposited in the field.

One object of my present improvement is to pY'GVlClG a corn harvester and shocker which is simple and light in construction. whereby it can be drawn by a single animal for simultaneously cutting and shocking two rows of corn.

Anotl'ier object of my present invention is to provide a novel mechanism for lifting; and holding the standing corn to be cut and car rying the cut stalks rearward to a shocking coinpartment in which it is collected to be tied into a shock.

."i further object of my invention is to gn'ovide the shocking compartment of a corn harvester with a removable bottom and a novel and improved manner of moving the liottom to open and closed positions.

Further objects and. advantages of the present improvement will appear from the following description and drawings, in which Figure 1 is a top plan view of a corn harvester and shocker embodying my invention, omitting the frontdraft'truck of the ma chine.

Fin. 10 is a diagrammatic view of the shocking; compartments showing the bottoms open-to discharge the shock therefrom.

Fig. 11 is a detached perspective view showing one of the gates for the outlet ends of the shocking compartments.

My improved harvester comprises two parallel combined corn stalk supporting and feeding. ways A, which extend longitudinal 7 the machine and terminate in longitudinally extending shocking: compartments B. These combined. supporting and feeding ways A are forme l by outer and inner vertical walls 1 and '2 the npper'edges 8 of each of these walls extending at an angle upwardly and rearwardly. As shown in Fig. l. the upper edgres of the walls 1 and 2 taper downwardly, whereby the combined supporting and feeding ways A are in side elevation approximately triangular in shape.

Shocking compartments.

4;, which are a. continuation of and in longitudinal lines with the outer walls 1 of the receiving and feeding ways A. Pivoted to the rear ends of the walls 4- are end gates which have their ends curred inwardly and close the rear ends of the shocking" compartments B when cl e ed shown in Fig. 1. The operation of these gates will be presently described.

The bottom of the inner walls of the shocking compartments comprise upwardly and inwardly inclined portions 6, which stationarily supported by the straps 6 which pass oycr and. are suitably secured to the parallel. bars This frame extends longitudinal the machine, as shown with its rear portion extending across the. niachi and its forward end (Z extending outward under the front ends of the inner walls 2 of the combined receiving and feeding; ways A.

' The upper portion ot the inner walls of the shocking compartment B are vertically and longitudinally movable and they comprise member D which is a 'iprorcimately U-shaped in cross-section as shown in dotted line Fig. 5., the'depem i of the member D comprising; upper portion of the inner walls of the shocking;- cor-apartments. The upper horizontal portion 8 ot the U-shape member: D is supported on a longitudinally extending bar 9, located at the under side of the horizontal portion 8. This bar 9 is supported upon the links 10 and 11, which have their ends 12 pivotally connected as shown in Fi 5 The upper ends of the linlzs 11 are plroted to the bar 9, at 13, and he lower enes of the bars 10 are pivotallysupported at 14, between the parallel stationary bars 15. These latter mentioned bars are supported in any suitable manner from the frame C by sn' .blc standards 16, which project upward oin e. rear portions of the trains A erating lever 17 has its lower end pivoted between the front ends of the stationary bars 4 and is connected with the bar 9, hr s table link 18. As shown in F" the We en s "Fthe linlrs are forwardly 'e' so tha t e ivo al poi re 12 are loed n a vertical p ane in front of the iro al points 14-. whereby when the opermr er is moved in the direction int by he ar oiin the bar 9 and the top lls D are moved upwardly and rearr. r h nrWSe oi slightly littim; t e shock as it is deposited upon the ,e'ron nd. I

The bottoms 19 of the shocking compartments B are inwardly movable for the pnr pose of opening the bottom of the shocking; compartments to deposit the shocks on the ground. This is accomplished by providing: two angle levers 20. for each of the bottonis or bottom-boards 19. These angular levers 20 are interniediatciy pivoted at 2; to the side portions of the n'iaihiue trade a. clearly shown in i i gy. while the outer ends of the lovers 20 are pivotally connected at 22 to the bottom boards 19. When the tree ends of the lovers 20 are moved by liulw 26 and 20 in the direction indicated by the arrow 5. the bottoms l. are swung itm'warrlly and inwardly. thus opening the bottom of the shocking compartments 3 to deposit the shock on the ground.

' be operating: lever is intermediatc y pirotcd between the forward ends of the stationary bars as shown in Fig. :i, and the lower end oi this lerer is connected with the inner free, ends of the augrlo lei'crs by suitable links 96 and Qdfl \vhcrebr when the lever is moved in the dire-Mimi indicated by arrow, the lovers 20 are move and swing: the bottoms l9 torwardl and inwardly, as descr bed At the same time that the bottoms i of? the shocking compartmcuis are opened the cycles 5 are moved on! wardl t open the rear cu oi' the shocking coinpartments, so that :ittcr the shock has been l'leposited on the irrcumli the machine is permitted to 111"? ilorward and the shock per mitted to pass out the res r end oi the shocking; compartment Th s movement o i the 5 is a ,coniplished by the movenuut oi' the lever 2% through a mechanism compris inc; :1 horizontal pivoted rod 527. carrying :u operatii arm 23 which arm is operativelv connecteo with the lever 94. by a suitable linlt 29. The outer crank-shaped ends 30 oi the bar 2? are connected with crank arms 'll i by means of linl 32. By this arrangement when the ope scion lever is moved in th direction indicated by arrow Fig to throw open the bottoms 19 ot the shocking compartments R the grates 5 at the sanic time swungopen by the mechanism just described.

Suitable reciprocat ng knives are located near the inner end ot the receiving: and tendin wars 1M and these reciprocating: knives co-opei ate with stationary knives 3 1- For cutting the corn that is ted to them in 1 manner to be explained presently. llhcsc lmives 33 are op rated by the combined supporting and driving; wheels in a manner which will now be described.

rotating she-l t 536 extends across the machine in rear of the knives 33. and this shaft carries a beveled gen r 37 meshing: with a beveled pinion 2-38, which is opcratively connected with the knife bar 39 by means of a connecting; rod 410i having its end 11 connected with a lmite bar and its opposite end connected with a crank 42 opcrativcly connected. with the beveled pinion 39, all of which is well understood by those skilled in this art, anrh therefore, need not Hit) l l O ed out.

melee? be more Fully illustrated or described. The outer ends of the shaft 36, carry loose sprocket Wheels 43, which are operatively connected with sprocket wheels 41-4. on the drive wheels by a sprocket chain 4-5. vSuitable spring actuated clutch members 46 are carried by the ends of the shaft which are operated by a lever ii", the lever being; connected with the clutch members 46, by suitable links 48. whereby the clutch members are thrown in and out of operation with the loose sprocket wheels 13, for the purpose of connecting and disconnecting; the drive wheels with the shaft 36.

Feeding madam/ism.

The means for feeding the corn stalks to the rnives and backward to the shocking compartments l3, consists of a plurality of ake members it. These rake members 2 are movably supported by the inner walls 2 of the t'eedways A. These ralic members E are supported in suitable cutting and support inp; ways 49 and 50, and these ways and rake members are arranged respectively in upper and lower pairs. The ways 49 and 5(l extend at an angle approximately corresponding: to the angle of the upper ed go of the side walls 1 and 2 of the teed-ways A, as shown clearly in i. The upper and lower rake members E are constructed alike, and their specific construction will be presently point- In operation the two upper rake members E are reciprocated in opposite directions. that is to say, when one of the rake members E is moved forward, the other is moved rearward, and vice versa. The same equally true of the lowerpair 0t rake members E. The means for reciprocating these rake members in the manner just mentioned will now be described. 7

A. horizontally beveled. gear 51 meshes with a beveled pinion 52 carried by the horizontal shaft 36., whereby the former gear is rotated. The shaft 53 ot the gear 51 is provided with oppositely extending crank arms 54:.

Twolevers 55 and 56 are interi'nediately supported at the point 57 between the inner walls 01": the teedways A, and. one of the ends of these levers 55 and 56 are respectively operatively connected with the cranks by the links 58,, so that the said levers are reciprocated in opposite directions. The ends oi these levers 55 and 56 are connected with the upper rake members it by upwardly and forwardly extending links 59. and with the lower rake member E by the links 60. Since the corresponding; ends of the levers 55 and 56 are reciprocated in opposite directions it will. be understood that the upper and lower pairs of rake members it are reciprocated in corresponding directions so that when one of the upper and lower rake members E are moving in one Rake members.

My improved rake members comprise a housing made up of two oppositely extend ing- U-shaped members 61 and 62, in which are mounted two reciprocating members 63 and 6d. The ti -shaped members are connected at their inner sides by sniiicient pum bers of connecting" bars 65. to firmly hold the U-shaped members in the relative positions shown. The reciprocatinn member 64; is provided with an inwardly projectimr ear 66 to which the ends of the operating l. .iks 59 and. are lGSPQClJlVEly connected. it. plurality of rake-fingers 67 have their inner ends 68 provided with lateral ends 68, which are pivoted in the reciprocating members 64; of the rakes, and these fingers 67 project through angularly extending slots 68 formed in the reciprocating): member 67"). The lower or forward ends oi" the members 33 are provided with inwardly extending" stop members b5) adapted to be en gaged by the adjacent lower and forward ends of the reciprooatiluz members M. The member (it is the operative member O'f the rake since it is connected with the operating crank shaft 53 and it has a limited reciprocating" m-iivement independent of the member *3 in both directions. The independent reciprocation in the direction indicated by arrow, Fin. 8.. is limited by the stop member 69 secured to the member 63 through screw openings 69 and the independent reciprocation in the opposite direction is limited by the limitation of the swinging or pivotal movement in the slot 68 of the member 63. That is to say the pivotally swinging movement oi the tii'iger is limited. by the end-walls oi the slots es.

l/Vhen the reciprocating rate members and 64: are moving; forward, the rake Ziup'ers are retracted or swung: backward. and wb the rake members are moved l'eai'warih fingers 67 are turned on their pivots and extended or swung outward to on go the corn stalks and move them rearward to the cutter knives and to the shock rompmt ments l3 and a. The extended and contracted movements oi the ra are etlected in the tollowinpj 1.1.1 the rake members at the limit 0 fr movement and the rake-lingers extender member 64* moves forward iiu )G's'itltlhi ot the. member 63 until the forward end of the member M engages the stop 69 'ied by the member 63. This independent movement swings the rake ti: o ers inward and from that point on the members 63 and (it move together to their forward position with the rake fingers contracted. l i hen the member 64.- starts rearwai. l moves independently of the member thus swinging lllb the ral-ze on their pivots and causing them to attend until they loch against the wall of the slot 68, when the two rake members move rearward together with the lingers extended for the piu'pose described. The member is held bet-ween the i-shape l members 61 and 62 with sufiicient friction to insure the member 6 ft leaving the indepcnzlent forward and rearward moven'ients explained for the purpose of retracting: and extending the rake fingers.

Draft truck.

The forward end of tie machine is provided with a draft trucl: I? This draft truck F comprises two wheels 70, mounted on an axle 71, and this is supported between depending arms 72. A l-shaped frame 78 has its rear ends pivoted at the point 74 to the sides of the front end (1 the frame C and a vertical pivotal rod 76 passes through the front end 75 of the frame 73, the bar 76 sting as a pivotal point f r turning the wheels horizontally in either direction. A suitable draft bar 7' 6 is con nected with the front truck in any suitable manner. Projecting upward from the front end of the frame 73 is an arm TS and a lever 79 is intermediately pivoted to this arm at 80 A U-shaped strap 81 has its lower ends 82 rigidly connected to the front end Z of the frame C, and it extends over the front end 75 of the frame 73. A suitable link 82 connects the top of this strap 81 with the front end of the lever 79.

By means of this construction, the front end of the frame C is raised and lowered for the purpose of regulating the height of the front end of the frame C. A depression of the lever 79 will lit the front end of the frame (Z upward through the intervention of the strap 8L and link 82 the frame 73 turn :ing on its pivot 7 and the front truck sustaining the weight of the front end of the frame (Z in any of its positions. For the purpose of holding the lever 79 in its depressed position, a suitable latch 83 is provided under which to hook the free end of the lever 79.

Suitable chain tighteners 8d are provided for the driving chains 45, to take up any slack that may be occasioned therein from wear or otherwise.

The rear ends of the feeder compartments a are formed by a plurality of spring held levers 85, which have their inner ends e):- tend-ing thereacross, as shown in Fig. 1. These levers are intermediately pivoted at 86 and are normally held with their inner ends extending across the rear portions of the feeding compartments o by suitable springs 87.

One or more platforms 88 are provided for the operator and driver. These plat forms are located substantially at the center of the machine where the levers 1T 2! and 4:7 can be readily reached from the plot forms for operation.

The outer ends of the outer *alls oi' the feed-ways A are braced by suitably arranged brace-rods S9 and 90.

tiling suitable axle is provided for the combined supporting and driving wheels Eli. but as here shown these aides comprise a U- shaped rod having trzv; verse portion hi and the lone turlinall extcudin poriiom 92. The axles A) for the wheels J arc formed by bending; the ends of the portions 92 outward at right augrlcs. as shown. supporting the axles 93 on the ends of a lJ-shaped bar. as described so places thc aide that it does not interfere with any of the mechanism of the machinc and makes the pull directly on the frame by attac|viu; the rod 91 to the said frame at the points 94- The rod 91 is prevented from oscillating; in its connections 94: by having the nner ends of the axles conne ted to thc lowci' edges of the outer walls 1, through the incdii m of connectingmembers 0:).

The front pointed ends of the feed-ways move under anv laterally cxteinlingr corn stalks, as the machine moves forward and lifts them to proper position to be fed by the rake members to the cutter li'uivcs.

The movable top walls D of the shocking compartments assist in relieving: the wcig'ht of the shock on the movable bottom. when the incl ned walls are lifted and facilitates the dumpingof the shock.

The cut stall-rs are fed rearward into the compartment a and packed up aoiainst the yielding members until the compartmculs a are filled and pressure on the corn stalks is sufficient to force the yielding members R5 rearward at which time the stallzs pass nto the shocking; compartment. hen the shocl-iin o; compartment is filled, the machine stopped and the tops of the corn stalks tied. together before the shock is dimmed.
